Err 999 My D50 has a flashing Err with a number 999 and it won't take any pictures. I can review pictures that I have taken but it won't take new ones. I can't find this code anywhere. Does anyone know what has to be done to get rid of this err and clear the camera for operation? Thanks!

I'm not sure what you mean by "multi-colour mode" but this page shows all of the possible playback display modes and describes them. Hopefully this helps you. I use a D7000 which is quite similar and I've never seen a multi-color mode. Nikon D50 SLR Review

When a Nikon camera says Err, something is wrong with the memory card. Perhaps it is not inserted correct. Or not a card inside at all. Perhaps you can't write to the card or it should be formatted.
When you have a Err, the camera won't do a thing, to avoid the user can think he is shooting pictures and the camera won't save one.

Contact Nikon tech support at www.nikon.com to see what they recommend. I don't think the warranty covers abuse such as dropping the camera so you may be in for an expensive repair. However, he Nikon techs may be able to suggest something that might help you avoid that expense.

You must take it or send it to Nikon it sounds like the computer went crazy and has to be calibrated you cant fix it yourself .

use it anyway

Does the flash work? Could be flash circuit or day/night sensor.If you have another D40/D50 camera that flash works but has other problems,swap out the sensors.If not the sensor but the flash circuit then most likely one of the large charge capacitors which has to be soldered in.I use a digital multimeter with I/O capacitor test function..these caps should be about 250mfd.

"err" is a cmara malfunction. If the camera has a hardware reset button, give that a try. If that does not work, then examination by an authorized Nikon Service Center is advised.

This is from the manual: "File numbers are reset when new folders are created." "New folders are created in the following cases: 1. When pictures are taken to folders containing files numbered 999. 2. When using cards already containing the same folder number (including pictures taken other cameras, etc.) 3. When recording after performing a 'NO. RESET' (found in the setup menu).

hi..
This screen shows areas of the photo that are overexposed slightly.
It flashes them to help you.
You get to this screen by pressing the up or down arrows when displaying the pictures you have taken.

To change it just press the up arrow when the camera is showing the screen until you get a display without flashing.

Once you have done this the display will be steady.
If you get any other screen in future you may have accidently pressed the arrow again.
Just cycle thru the displays to get back to steady.

thank u
rate me!!

Try resetting the camera.

First a soft reset is to just replace the battery. If that doesn't work try a hard reset - on the bottom the other side to the battery flap.
